Abstract

Una señal que representa un grupo de planos de objetos vídeo codificados por compresión (VOP), incluyendo cada plano de objetos vídeo una secuencia de cuadros de planos de objetos vídeo multiplexados en el tiempo de cuadros de planos de objetos vídeo codificados intracuadros (cuadros I-VOP), cuadros de planos de objetos vídeo codificados predictivamente (cuadros P-VOP) y cuadros de planos de objetos vídeo codificaciones bidireccionalmente (cuadros B-VOP), teniendo dicha secuencia de cuadros un orden de visualización previsto y donde los datos para cada cuadro de planos de objetos vídeo están prefijados por datos de temporización codificados, caracteriza porque: a) cada uno de dichos cuadros de planos de objetos vídeo codificados intracuados (cuadros I-VOP) y cada uno de dichos cuadros de planos de objetos vídeo codificados predictivamente (cuadros P-VOP) incluye datos codificados que definen una base de tiempo de referencia, b)dichos datos de temporización codificados para cada cuadro de planos de objetos vídeo incluye dos componentes, el primero de dichos componentes representa un módulo de base de tiempo (MTB) y el segundo de dichos componentes es un incremento de base de tiempo; y c) dichos cuadros de planos de objetos vídeo codificados bidireccionalmente (cuadros B-VOP) tienen un tiempo de presentación obtenido añadiendo el módulo de base de tiempo decodificado (MTB) y el incremento de base de tiempo a la base de tiempo de referencia obtenida de la orden de visualización que precede al cuadro de planos de objetos vídeo codificados intracuados (I-VOP) o el cuadro de planos de objetos vídeo codificados predictivamente (P- VOP), respectivamente.
